Title: Improvements in and relating to the steam reforming of hydrocarbons
Inventor: BATES ERIC BILLINGSLEY
IPC: C10G11/22
Filed: 1962-08-22
Abstract: In a process of steam-reforming liquid or gaseous hydrocarbons of the kind reformed in Specification 1,032,751, the following conditions are observed: in a primary (endothermic) reforming step with a catalyst the temperature is at least 650 DEG  C. and the liquid space velocity at least 0.5 per hour; in a secondary (exothermic) catalytic reforming step the temperature is in the range 450 DEG  to 750 DEG C. (preferably 500 DEG  to 680 DEG  C.) at a pressure of at least 100 p.s.i.g.  The temperatures and pressures for the secondary step, and the steam ratio, are selected in accordance with plant and catalyst dimensions and space velocity to give a product gas having an equivalent methane content (i.e. that quantity of methan having the same c.v. as that of the hydrocarbons present in the gas) of at least 20% by volume, and the space velocities of both steps, and the dimensions of the secondary reformer, are such that non-methane hydrocarbon entering the secondary reformer is reformed to at least 95% by volume. "Non-conversion" and "liquid space velocity" are defined for normally liquid and normally gaseous hydrocarbons. Pressure up to 600 p.s.i.g. and space velocities up 1.3 per hour are mentioned in the secondary reformer, and steam ratios ranging from 1.3 to 5.5, depending, inter alia, on the catalyst, which may be of the kind described in Specification 1,032,751.  Further hydrocarbon may be added to the gases leaving the primary reformer, and a cooling stage, e.g. by heat exchanger, may be interposed between the two reformers, or product gas may be recycled after suitable temperature adjustment to the secondary reformer which may comprise several stages.  Alternatively, the secondary reformer catalyst may be cooled indirectly and the heated coolant used to heat the primary reformer. The product gas may be modified or enriched as described in Specification 1,032,751.  Five specific examples are described.

Title: Improvements in feed mechanism for the record strip of cashregisters
IPC: B41J15/02
Filed: 1932-11-16
Abstract: 393,487. Cash registers &c. PANTHERWERKE AKT.-GES., 24, Ludwigstrasse, Brunswick, Germany. Nov. 16, 1932, No. 32357. Convention date, Nov. 17, 1931. [Class 106 (i).] Item-printing mechanism.-In a cash register or like machine having a record-strip feed-mechanism of the kind that in addition to effecting line-spacing moves the portion of the strip to be printed from an inspection position to a printing position and back again to the inspection position, the winding-up and winding- off rolls for the strip are arranged at equal radii and diametrically opposite to each other on a revoluble disc or other member which is rocked by the operating mechanism. The winding-up roll 16 and winding-off roll 17 are rotatable on studs projecting from a disc 13 fast on a shaft 12 rocked by the main shaft during each machine operation. The strip 23 passes from the winding-off roll over a roller 53 on the disc, thence via rollers 43, 44, 42, 41 on a rockable printing frame 39 to a second roller 54 on the disc and to the winding-up roll. The clockwise rocking of the disc causes that part of the strip that is to be printed to move from a position a, b beneath an inspection and autographic opening 57 to a position below the roller 44 which serves as a platen. After the frame 39 has been rocked to effect printing, the strip is returned to inspection position by the counterclockwise rocking of the disc. Line-spacing is effected by a pawl 24 pivoted to an arm 27 and spring-urged into engagement with a milled disc 23<1> rigid with the winding-up roll. The arm 27 is free on the roll-supporting stud and during the clockwise movement of the disc strikes a pin 38 projecting from the printing frame, its resultant counterclockwise rotation effecting the feed. The angular extent of the feed is controlled by a cam disc 29, a rise 36 on which co-operates with a pin 35 on the pawl 24 to raise the pawl out of operation. The cam disc is angularly adjusted by a feeler arm 34 that presses against the surface of the roll of strip and is provided with a pin 31 movable within a slot 30 in the disc. The arm 27 is returned to normal position by engagement with a pin 37 during the return movement of the disc 13.

Title: Improvements in or relating to windscreen wipers
IPC: B60S1/08
Filed: 1925-12-24
Abstract: 258,139. Melmore, W. M. Dec. 24, 1925. Windows and the like, cleaning. - Windscreen wipers are provided with a delay action device comprising a dashpot or the like associated with the wiper-operating means, so that repeated operation of the wiper is delayed for a predetermined interval of time. Specification 230,220 is referred to in which an electric solenoid and plunger are provided with automatic means for intermittent operation. The present invention is not necessarily confined to the solenoid and plunger type. A plunger 1, Fig. 1, actuating a wiper 2 has a rod 3 provided with a cup leather 4 reciprocating into a cylinder 5 open at one end, and with a finely adjustable air inlet cap 6. Air leakage occurs past screw threads on a rod 7 and can be adjusted by rotation of the cap 6. A spring 8 tends to withdraw the rod 3 from the cylinder. An abutment 9 on the rod 3 contacts with a pivoted switch arm 10 to engage a movable contact 12 on the arm with a fixed contact stud 13 or two dummy contacts 14, 15. The cylinder 5 is formed in an ebonite block 16 which is extended forwards to serve as a mount for the studs 13 &c. A spring presses the switch arm 10 into electrical contact withe the studs 13 &c. On the rod 3 is slidably mounted a member 18, Fig. 2, with a contact end 19 to fit into the cup leather 4 while the other end 20 acts as an abutment on which the member 9 can strike. A roller 21 carried by the arm 10 engages between the ends 19, 20 of the member 18. Current passes through the solenoid 22 so as to operate the plunger 1 sharply inwards, and continues through the switch 10 and stud 13. The cup leather 4 is forced into the cylinder 5 against the spring 8 and the member 9 strikes the member 18 moving the switch arm 10 to cut off current. The cup leather 4, rod 3, &c., returns slowly against the action of spring 8 as air leaks into the cylinder, but when the cup leather 4 is free of the cylinder it moves quickly to strike the member 18 switching the arm 10 into contact with the live stud 13. To retain the wiper out of use, a spring 29 is allowed to engage a notch 30 in the plunger 1 and hold it. The plunger 1 is, when in operation, prevented from sliding so far by a movable cam 24 provided with a handle 27. Instead of electrical control by the switch 10, valve control means might be substituted for a power operated wiper.

Filed: 1972-07-12
Abstract: 1398632 Making tampons DR CARL HAHN GmbH 12 July 1972 [15 July 1971] 32658/72 Heading A5R [Also in Division B8] Tampons are produced from an endless fleece strip by forming lengths of the strip into rolls or coils in an intermittently operating coiler 1 and conveying the rolls to an intermittently operating press 2 by means of a transfer apparatus which is such that adjacent the coiler the rolls are moved intermittently but near the press the rolls are moved continuously.. Tampons are transferred continuously from the press to a store and a packaging station. Two coilers 1 supply rolls to chains 15, 16 each carrying cups 20 and being driven intermittently via sprockets 9b from the corresponding coiler through a dog clutch mechanism, and driven continuously near the press 2 by a sprocket 42 driven from the press. Between the coiler and press each chain passes round two reversing sprockets 17a carried by a rod 17 which can reciprocate horizontally. A roll is ejected from the coiler into a cup 20 by a push rod, means being provided for disengaging the clutch if a faulty roll is received in cup 20 so that the chain remains stationary at the coiler while another roll is prepared and ejected into the cup to dislodge the faulty roll. Stoppages of the drive at the coiler cause rod 17 to move in direction 18. The end positions of rods 17 are sensed by limit switches which transmit signals to stop the coiler or press. Means are provided whereby if the rods 17 stop in different positions, rolls continue to be ejected from the chain corresponding to the rod displaced in direction 19 until the chain has emptied to the extent that the rods 17 are in the same position. At the press 2 each chain passes round two reversing sprockets 12 having centrally disposed push rods to eject rolls from the cups 20 for formation into tampons. The tampons are transferred in turret 3 to tampon cups 13 carried by continuously rotating chains 21 during reversal of the cups 13 round reversing sprockets 34. The tampons are then transferred to tampon receptacles 14 on a chain 22 at two transfer stations where the chain passes round two hollow shafts 10 each having four push rods 40 mounted in passages therein. The rods are reciprocated by rollers 39a secured to damping elements 39 and engagaing a cam surface 36. The completed tampons then pass to a store 5 and packaging station 7.

Abstract: 926,530. Ammunition fuzes. RHEINMETALL G.m.b.H. Sept. 23, 1960 [Sept. 26, 1959], No. 32858/60. Class 9 (1). A percussion fuze for rotated projectiles, which is provided with self-destruction means, comprises a body 1 housing a laterally movable asymmetrical striker 4 and closed by a baseplug 2 carrying a detonator 3. During transport the striker pin 5 is held out of alignment with the detonator 3 by engagement in a groove 9 having a chamfered side wall 10, the striker being secured in this position by a spring 7 surrounding the forward end 6 of the pin and extending into the nose of the fuze. The centre of gravity S of the pin lies outside the longitudinal axis of the fuze. A helical spring 11 arranged transversely of the fuze serves to delay movement of the pin 5 to the armed position. After firing a projectile fitted with the fuze, until acceleration ceases, the pin is held in the safe position by inertia. When acceleration ceases, centrifugal force due to spin causes the pin to slide over the side 10 and assume the position shown in Fig. 3, the movement of the pin being delayed by the turns of the spring 5. Spring 7 straightens and the fuze is armed for operation on impact. If, after a given time, impact does not occur, due to decrease in centrifugal force and the oblique seating 13, spring 7 operates the strikes to bring about self-destruction.
